Earth Day

Earth Day is 22 April, a day for the environment, observed in many countries.

The first Earth Day was held in the United States on 22 April 1970. Senator Gaylord Nelson called for it, and Denis Hayes coordinated it, after the 1969 Santa Barbara oil spill and a wider environmental movement. In 1990 the day was marked across many countries. The United Nations General Assembly later proclaimed 22 April as International Mother Earth Day.

Nelson called the 1970 events a national teach-in. The United Nations designation of 22 April as International Mother Earth Day is General Assembly resolution 63/278, adopted in 2009. The Paris Agreement was opened for signature on 22 April 2016.
